RM CL51 not booting from CD
Iv got an old RM CL51 which I wanted to use as a linux machine and general muck about machine, thing is I cant get the thing to boot off the CD, Iv set it as the first boot device in the boot order, and when I start it up I get a boot menu however when click CD it refused to read from it and just flick up with the boot menu again.
I know the CD works I can here it whirring and stuff, and even had it replaced cause I thought the drive might be damaged, but the new drive acts the same. I have noticed it has a RM BIOS but, looking at the RM site there are no BIOS updates. On first getting the machine I got it working by copying the Windows CD onto the harddrive the plugging it in the laptop, but obviously it would be far easier to get it boot boot from CD.
Can anyone help or offer explanation as to why it wont boot from CD?
